Abstract
Shear design of reinforced concrete beams with T section considers only the contribution of the web, mainly provided by aggregate interlock. However, as the load increases and large web crack openings take place, aggregate interlock reduces and shear stresses tend to concentrate near the neutral axis, usually located in the flanges of T beams, whose contribution to shear strength may be not negligible, as it has been experimentally observed. Thus, the contribution of flanges may drive to conside...
